Be it known that I, EDMoND.BosDEvEX,-o Phil-adelphia, Pennsylvania, have invented an Improved Grate for Stoves, Ranges, Sie.; and I do hereby declare the following to be a full, clear, and exact description'o'i` the same.,A v

VMy invention consists of a permanent grate and a hinged grate, adapted to each otherand to the fireplace of a stove or range, substantially asdescribed hereafter, so that the space for containing the fuel maybe vexpanded and contracted at pleasure, and so that the upper surface of the fuel may be always maintained in close proximity t`o the culinary vessels above the replacef v In order to enable others skilled in the art to make and use my invention, I will now proceed to describe its construction and operation, reference'being had to the accompanying drawing, which forms a part of this specification, and in whichy Figure 1 is a vertical section of my improved grate for stoves, ranges, Sto.

Figure 2, a plan view. i

Figure 3, a transverse vertical section on the line l 2, iig.; 1, showing'the movable portion of the grate lowered; and l I Figure 4, the same, with the movable grate elevated.

Similar letters reler to similar parts throughout the several views.

A and -A represent the sides of the fireplace, andare made hollow in the present instance, so'asto be serviccable as water-heaters. l l l In front of the replace, and between the sides A. and A ofthe same, is secureda grate, B, of the'curv'ed form represented in figs. 3 and 4; and at the rear of the replace is a grate, D, provided with-projections@ one of which is adapted to a recess in the hollowside A, the other to a recess in thehollow side A.- oi the ire` place, to which the grate is thus so hinged that it can be lowered, as seen in fig. 3, or raised, as seen in iig. 4.

The rear ofthe grate B is` made in the arc of a circle,`oi` which the axis ofthe hinged grate D is the centre, so that no matter whatmny be the position to which the grate D has been adjusted, its 'lower edge is always in closefproximity to the rear of the grate B. 4

To u. lug, e,.on one of the end bars of the grate, is hinged a link,f, havingatits lower end van eye for receiving the end of a rod, by operating which, from the front of the fireplace, the grate D may be raisedor lowered at pleasure, the link catching'against any` of the projections on a rack, L, secured to one ofthe sides of the fireplace, ,so that the grate will be maintained in the position to which it has been adjusted.

Other devices, equivalentto and as ei'ective' as that described forope'rating and retaining the grate, will suggest themselves; it does not, therefore, constitute an especial feature of my invention.

A As seen in iig.3, the space for .the fuel has been expanded to its full extent, by depressing the grate'D. It can be contracted, however, from time to time, as the fucl is consumed and decreases in quantity.` The extent of the upper surface of the fuel is, however, not materially diminished by elevating the grate D; Zand this -upper surface of the fuel,the most' available for heating purposes, may always he maintained in close proximity to the culinary v`essels above the fireplace.

The delay caused in cooking abovel ordinary fireplaces, owing to the necessity ofsupplying the sinking firefrom time to time with fresh fuel, is obviated by the above-described invention, which possesses the further advantage of economizing. fuel. i p

i Although have shown the permanent and hingedgrates as being arranged between two hollowsides of a fireplace, it will be readily understood that they can be adapted to fireplaces of dilierent styles without any difficulty. l

I claim as my invention, anddesire to secure by Letters Patent- 'lhe combination' of a permanent grate,'iB, and a grate, D, hung to the rear side of a replace, and capable of such adjustment that its front edge may' be brought to any desired position onthe grate B, for the purposedescribed.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
